Batch updates doubt
Guys I have a doubt. We already know january batch is full for update and rework, so even if nico/karolina gets nerfed, the nerf won't go live until next June right (second batch for next year). If that's the case I'll still invest in those champs since you can get a lot of value before they get nerfed, it justifies the resources.
This assuming kaboom follows the rule for nerf like they do it for buffing champs, which I'm not sure they won't hesitate to break rules to fix a "pro player detrimental effect".
